and more especially to walls of buildings comprising stanchions and sheet metal panels which are fixed to these-stanchions. V

5 It is an object of myinvention to provide means whereby the panels can be mounted in the wall in an exchangeable manner in order that panels affected by "corrosion or the like can easily be replaced.

1 It is another object of my invention to provide means for constructing the'panels from thin sheet metal in order to keep their price low enough to allow them to compete with stone walls, without however allowing the sheet metal to crumple.

I am enabled to obtain all this by forming the stanchions on one or bothsides of the wall with however, also combine an outer shell composed of sheet metal panels withan inner shell of heat insulating material or vice versa, and I may line a sheet metal shell with heat insulating or other material. a a

In order that the panels may be readily attachable to the stanchions, flanges extending in the plane of the wall may be provided on either side of the longitudinal grooves formed in the stanchions, and the panels may be fixed to these flanges by means of screw bolts or the like. I

may also provide ledges, preferably of. wedge shaped cross section which fit into the grooves ,and serve'to exert pressure on theinarginal portions of the panels projecting into these grooves so as to retain them therein, these ledges being held in'position in the grooves by means of tens sion rods or the like extending into the grooves. I thus-obtain a sheet metal'structure which", while being very simple in design, ofiers a very strong and solid connection between the panels and stanchions, since the panels, which in view of the camberimparted to them possess a rigidity of their own; are fixed to the stanchions over theirentire length and their bent marginal portions, which project into and are held in position 65 in'the longitudinal grooves of the.-stanchions,

My invention relates to sheet metal structures are protected against deformation by forces acting on the panels. This solid connection is the more important, since the-sheet metal panels are partly relied upon to take, up the stresses arising in the plane of the wall." 5 In order to increase the rigidity of the struc 'ture and to render the wall substantially watersides with bent marginal flanges projecting into grooves formed in the skeleton structure; 7, '10

In the drawings aflixed to this specification and forming part thereof sheet metal structures and parts of same embodying my invention are illustrated diagrammatically by way of example.

In the drawings l5v Fig. 1 is a perspective view of part of a sheet metal wall structure according to this invention and Fig. 2 is a horizontal cross section of a wall of this kind drawn to a larger scale and showing 20 how different parts of the wall are connected with each other at a corner.

Fig. 3 is a vertical section on the line IIIHI in Fig. 4, and Fig. 4 is a horizontal section on the line IVIV in Fig. 3, of part of a wall, in 25 which the marginal portions on all four sides of the panels are bent to form flanges projecting into grooves in the skeleton structure.

Fig. 5 is a perspective view of a sheet metal panel according to this invention, viewed from 30 the rear side ofthe wall.

Figs. 6 and 7 are a perspective view and a cross section, respectively, of a modified form of sheet metal stanchions and the parts connected therewith. 35

Figs. 8-10 are cross sections of three different modified forms of-stanchions adapted for use in the construction of a sheet metal wall structure according to my invention Referring to the drawings and first to Figs. 1 .10

inwardly to form flanges l4, l5, which project into'the grooves I00 and I0], respectively, being 50 fixed-in position by means of screws l6 entering threaded borings of the flanges I, 8 of the stanchions. Packing material I1 is forced into- ,the interstices between adjoining flanges to fill the gap, The stanchions are preferably braced by means of tension rods I8 and tubes I9 or by similar means. a

In the wall shown in Figs. 3 and 4 the stanchions are formed of two parts II and I2 only, the middle portions of which are in direct contact with each other, being fixed to each other by rivets I02, while their outer portions diverge to form the longitudinal grooves and flanges serving to fix the panels in place. project the bent marginal portions I4, I5 of the panels 4, 5, one of which is shown separately in Fig. 5. As shown in the drawing, the middle portion of the panels is depressed inwardly and formed with flanges I5 on their long sides and flanges 25 on the short sides, the flanges being connected with the corners to form a continuous circumferential flange of rectangular configuration. Inclined faces 2I connect the depressed main part to the short circumferential edges. The short portions of the flange project into horizontal grooves formed between the sheet metal strips 26 and 21 at the foundation 30 and 28, 29 at the ceiling 3| (Fig. 3), the gaps being filled with packing material I1, which effectually prevents the entrance of moisture, air and the like. This tight fit of the panels in the skeleton structure is particularly important in the case of double walls since here the interior of the walls is not accessible for inspection, so that the panels might suffer corrosion from the inside, if moisture were allowed to enter.

The stanchions illustrated in Figs. 6 and 7 are formed of a pair of deep narrow channels 35, 36, rigidly connected by means of cross stays 39, flat iron bows 31, 38, being interposed between the channels 35, 3'6 and stays 39, which take up forces arising in horizontal direction, which might otherwise cause deformation of the channels 35, 3B, the bows 31 at the same time serving for'flxing the channels in place by means of screws I6 or rivets.

The stanchion shown in Fig. 8 is formed of two sheet metal channels M, 42, the middle portions I03, I04 of which are depressed to different depths and fixed to each other by means of screws I05, the grooves 43, 44 thus formed serving to receive the marginal flanges of the panels, while the flanges 45, 46 of the stanchion apply themselves against the panels from the inside.

Fig. 9 illustrates a composite stanchion com- Into the grooves prising an inner pillar having the form of a rectangular tube, which is enclosed between sheet metal channels I06, I01, the outer portions 5I, 52 of which enclose between them grooves 53, 54 and are bent in opposite direction to form supporting flanges 55, 5B.

The stanchion shown in Fig. 10 is composed of a middle part 51 having the form of an I-rail, the flanges of which are embraced by bent sheet metal strips 58, to which are riveted the channels 48, 49 forming the longitudinal grooves and flanges for the reception of the panels.

I wish it to be understood that I do not desire to be limited to the exact details of construction shown and described for obvious modifications will occur to a'person skilled in the art.

I claim:

1. Sheet metal wall structure comprising in combination, flanged sheet metal channels arranged in pairs with oppositely directed flanges and united to form stanchions with longitudinally extending grooves, pairs of inwardly depressed sheet metal panels inserted between each of two adjoining stanchions, convex sides of said panels facing each other and inwardly bent marginal portions of said panels projecting into the vertical grooves of said stanchions, packing material in the grooves filling the interstices between adjoining flanges and means directly securing each panel to the flanges of the channels.

2. Sheet metal wall structure according to claim 1, comprising bracing means connecting adjoining stanchions.

3. Sheet metal wall' structure according to claim 1, wherein a stanchion comprises a pair of U-shaped parts extending in opposite direction and inter-connected in spaced relation to each other so as to form said grooves.

4. Sheet metal wall structure according to claim 1, wherein a stanchion comprises a pair of flanged parts riveted together near the center but bent so as to form said grooves near said flanges.

5. Sheet metal wall structure according to claim 1, wherein a stanchion comprises two flanged U-shaped parts, and means extending in the direction of said grooves connecting said parts.
